Answer:
total = 0
for i in range(4):
bill = float(input("Enter bill for quarter " + str(i+1) + ": "))
total += bill
average = total / (4 * 3)

print("Average monthly bill is $" + str(average) + ". A typical amount of water is being used")
if average < 25:
print("Average monthly bill is $" + str(average) + ". Thank you for conserving water")
